PRODUCT INFORMATION BSFJ78G25 Satellite Tuner RF Components Group APPLICATIONS: • Satellite receiver • Data receiver • Wide-band front end FEATURES • Digital AFT out • Standup Package • AGC sample out • Compact, lightweight design (22 cc) • Electronic tuning with frequency synthesizer DESCRIPTION The BSFJ78G25 is an integrated single conversion tuner and FM demodulator. It was designed for the reception of analog signals. It has a dual input and a combined video and audio output. The input frequency range is 900 to 2,150 MHz. A 27/18 MHz switchable bandpass filter is positioned at the first IF. Bandwidth selection is made by applying an external voltage via an external pin. A digital AFT output is provided for evaluation of receiver system accuracy. This tuner can be controlled by an internal three wire PLL interface. A 1/256 prescaler is internal to this tuner and provides the ability to interface with the PLL. For more information on this product, please contact your local Sharp representative.
